High-Speed 64K x 8 Dual-Port Static RAM
Description
The IDT7008 is a high-speed 64K x 8 Dual-Port Static RAM. The
IDT7008 is designed to be used as a stand-alone 512K-bit Dual-Port RAM
or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more
word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach
in 16-bit or wider memory system applications results in full-speed, error-
free operation without the need for additional discrete logic.
This device provides two independent ports with separate control,
address, and I/O pins that permit independent, asynchronous access for

Military, Industrial and Commercial Temperature Ranges
reads or writes to any location in memory. An automatic power down
feature controlled by the chip enables ( CE 0 and CE 1 ) permit the on-chip
circuitry of each port to enter a very low standby power mode.
Fabricated using IDT’s CMOS high-performance technology, these
devices typically operate on only 750mW of power.
The IDT7008 is packaged in a 84-pin Ceramic Pin Grid Array (PGA),
a 84-pin Plastic Leadless Chip Carrier (PLCC) and a 100-pin Thin Quad
Flatpack (TQFP).
